摘要： In some implementations, a computing device can transfer a playback queue between the computing device and a playback device. For example, the computing device can detect when the computing device is within a threshold distance of a playback device. The computing device can establish a connection to the playback device and receive state information describing the media playback state of the playback device. The computing device can determine the media playback state of the computing device. The computing device can present graphical user interfaces for initiating a transfer of a playback queue between the computing device and the playback device based on the playback state of the devices. The computing device can initiate a transfer of the playback queue in response to user input to one of the graphical user interfaces or automatically based on the context of the computing device.

摘要： In some implementations, a computing system can be configured so that a first user device can delegate a first user's media account credentials to second user device corresponding to a second user. For example, a playback device may be configured with a the second user's media account credentials for accessing media items through a network media service. A first user may wish to play media items associated with the first user's media account credentials on the playback device. To do so, the first user device can request a device identifier for the playback device, request and obtain a delegate token for the device identifier from the media service, and provide the delegate token along with media item information to the playback device. The playback device can then use the delegate token to request the media item associated with the first user's media access account.

摘要： Method and apparatus to prevent hacking of encrypted audio or video content during playback. Hackers, using a debugging attachment or other tools, can illicitly access encrypted data in memory in a playback device when the data is decrypted during playback and momentarily stored in digital form. This hacking is defeated here by methodically "poisoning" the encrypted data so that it is no longer playable by a standard decoder. The poisoning involves deliberate alteration of certain bit values. On playback, the player invokes a special secure routine that provides correction of the poisoned bit values, for successful playback.

摘要： Methods, media and systems that use an encoded opaque pointer in an API between a client process and a library process. An encoded opaque pointer, in one embodiment, can be received by the library process from the client process, and the library process can decode the opaque pointer to obtain an address in memory containing a data structure pointed to by the opaque pointer. The library process can operate on the data structure to create a revised or processed data structure, stored in the same or different address in heap memory or stack memory, and the library process can encode and return a new opaque pointer, for the processed data structure, to the client process.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for obfuscating a computer program. A system configured to practice the method identifies a set of executable instructions at a first location in an instruction section of the computer program and identifies a second location in a data section of the computer program. Then the system moves the set of executable instructions to the second location and patches references in the computer program to the set of executable instructions to point to the second location. The instruction section of the computer program can be labeled as_TEXT,_ text and the data section of the computer program is labeled as_DATA,_ data. The set of executable instructions can include one or more non-branching instructions optionally followed by a branching instruction. The placement of the first and second locations can be based on features of a target computing architecture, such as cache size.

摘要： Method and apparatus for marking individual video frames of an H.264/ AVC standard compliant or equivalent digital video stream. Each video frame in a H.264/AVC video stream is conventionally divided into NAL units. There are typically a number of NAL units for each video frame. There is specified in the H.264/AVC standard the SEI (Supplemental Enhancement Information) type. This type includes the user data unregistered type, which can contain arbitrary data. In the present method and apparatus, an NAL unit of this type is provided at the beginning of each video frame, preceding the other NAL units associated with that video frame. The data contained in that special SEI unit is typically control information for downstream control of use of the video content. Examples of the type of control information are stream positioning data such as a video frame number; stream bit rate, such as normal, fast forward; decryption data, such as a decryption key or key derivation seed; and validation elements, such as a checksum or hash function value or signature.

摘要： An integrity verification process and associated apparatus to detect tampering or other alterations to computer code (software) or other computer files, and especially useful to detect tampering with code by hackers who might try to plant their own malicious code in the software. To make the verification process more robust versus hackers, each e.g., object code file to be protected is first selected using some sort of rule, then partitioned into variable length blocks or portions, the lengths varying in an unpredictable manner. Each portion has its checksum or hash value computed. An accompanying verification file is created which includes a vector for each portion including the portion's start address in memory, length, and the computed checksum or hash value. When the code is later to be run (executed) the verification file is conventionally read and each portion is verified by computing its checksum or hash value using the same algorithm as before, and comparing that to the value in the associated verification file vector. Lack of a match in the two values indicates tampering, so execution of the code can be halted.
摘要翻译：完整性验证过程和相关联的设备，用于检测对计算机代码（软件）或其他计算机文件的篡改或其他更改，并且特别有用于检测骇客可能尝试在软件中种植自己的恶意代码的篡改代码。为了使验证过程比黑客更健壮，每个例如待保护的目标代码文件首先使用某种规则来选择，然后被分割成可变长度的块或部分，长度以不可预测的方式变化。每个部分都有其计算的校验和或散列值。创建伴随的验证文件，其中包括每个部分的向量，包括部分在内存中的起始地址，长度以及计算的校验和或哈希值。当代码稍后运行（执行）时，常规地读取验证文件，并且通过使用与之前相同的算法计算其校验和或散列值来验证每个部分，并将其与相关联的验证文件向量中的值进行比较。两个值中缺少匹配表示篡改，因此可以停止执行代码。
